Accupro 14788352 Square End Mill 2 Flute 1/4 Inch Carbide

Product Description

The ACCUPRO 14788352 is a 2-flute solid carbide square end mill designed for precision milling operations in metal and composite materials. With a 1/4-inch mill diameter and a 3/8-inch length of cut, this end mill delivers clean, flat-bottom cuts and sharp corner definition on finished surfaces. The centercutting geometry allows direct plunge entry into the workpiece without a pilot hole. A 38 to 42 degree helical flute angle promotes efficient chip evacuation and reduces cutting forces during slotting and peripheral milling passes. Machinists and tool-and-die professionals are the primary users of this tool in CNC and manual milling setups.

This end mill is suited for light to medium-duty milling applications in job shop, production, and toolroom environments. The 1/4-inch cylindrical shank fits standard ER collets, end mill holders, and milling chucks commonly used on vertical machining centers, knee mills, and CNC routers. The 2-inch overall length keeps the tool compact and rigid, reducing deflection during high-precision cuts. It is appropriate for ferrous and non-ferrous materials where a solid carbide substrate provides the hardness and wear resistance required for consistent tool life.

Key Features

• Solid carbide construction for high hardness and extended wear resistance
• Centercutting design allows direct plunge milling without pre-drilling
• 2-flute helical geometry promotes efficient chip clearance in slotting operations
• 38 to 42 degree helix angle reduces cutting forces and improves surface finish
• 1/4-inch cylindrical shank fits standard collet and end mill holder systems
• Compact 2-inch overall length maximizes rigidity and minimizes deflection

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide square end mill for 1/4-inch collet and end mill holder tooling systems on CNC machining centers, knee mills, and CNC routers.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for toolholder torque and runout specifications. Power down and lock out the machine spindle before inserting or removing the end mill from the holder. Verify collet condition and cleanliness before seating the shank to prevent runout and premature tool wear. Do not exceed the recommended depth of cut or feed rate for the workpiece material and machine capability.
